Appucaiibn linea lnecesitar 7, 1923.' sevi'iai'ntfeaieai To ctZZ'Lc/wfnm'tmay @office/n.: f 'i i t Be it knownthat I, FRANnronnMiCpon, a citizen of the UnitedStates, residing at 1 Sedalia, in ythe county of Pettis and State of Missouri, have invented a new and useful Indicator, of which thefollowmg-isa specification. f

This invention aims to yprovide a simple device in which, through the inanipul'ationfof movable disks, the prices of'merchandise may be exhibited to prospectivepurchasers` as the prices change,the device being offutililly' ill the hands of vendors of gasoline 7and other commodities. Y. f

It is within the province of' the'f'disclo-- sure to improve generally and to enhance the utility of devices of that type to which the inventionappertains. v l

vWith the above and other objects'in-view,

which will appear as lthe description pro-v ceeds, the invention resides 'in the combination and arrangement o-f parts and in the details of construction hereinafter described and claimed, it being 'understood thatr changes in the precise embodiment ofthe invention shown, can be made,y without departing from the spirit of the'ginvention.A In the yaccon'ipanying drawingsi `l Figure 1 shows in elevation, a device, constructed in accordance with thefinvention; Figure 2 is a section on'the line 2-2 ,of Figure 1'; Figure 3 is an' elevation wherein one of the outer plates has been'- removed; Figure l is a section on the line i-i -of Figure l. y *y 1f f Y The device forming .thesubject matter of this application is made of any suitable inaterial and comprises outery plates 1 between which is located'amarginal spacer 2 of rectangular outline, as shown in Figure 3, the plates 1 and the spacer 2 being held together by securing elements 3. An adjustable pivot member 4, which may be a bolt and wing nut, passes through the outer plates 1 at the geometrical center of the frame. Pairs of pivot elements aremounted in the plates 1 and are located between the median transverse line of the frame and the ends. thereof. Main openings 6 are formed in the outer plates l and are located in the median longitudinal line of the` frame. The main opening 6 of one plate `located on one side of the pivot member 4, and the corresponding opening in the otherplate 1s located on the opposite side of the pivot member, as shown in Figure l. kAuxiliary 'openings 7 are fashioned in the plates 1,`ony

opposite,sides of ythe pivot, membeifik and arerlocatedbetween the; openings 6 and the ends ofth'e frame. yThe openings 6 are elongated longitudinally VVof the frame, the openings, being elongated transversely j of V the frame. 'A character 8, denotingia standard of value, is inscribed on the outery sur- .face ofthe plate Y1, between the opening 7 tion line 5. The partition line l9 on each of sand the end of' the frame. f On the inner surface of each plate 1' is inscribed a parti` the plates'l-is visible through ithe auxiliary openingf? in the'other plate, as *clea'rly shown in Figurel. Each.plate 1 maybe provided on its outer surface, :and preferably at'itsgeometricalcenter, with an indexVV ing 6. "l

The "inner disk 11 is suppliedon both sides,fwith numerals 12, visible throughthe Vopenings ,7 c, the `numerals being 'so uinscribed on thev opposite surfaces of the disk 11 that the numerals maybe @read from either side of the frame,l withoutinverting the fra'mef-anV observa-r tion which willbe understood readily when L the ,dotA and dash showing of Figure 1 is Y noted-.5.7Outer'idisks lvaremounted to ron itate on the4 adjustable pivot member 4L and are:located'betweenf'the inner disk 11 on the one hand, and the outerffplates 1.y on the other hand.vr The outer disks 14 are-of less diameter thanv tl-iefinner disk 11, fso that the numerals l1.2 on the ,inner disk will re- A' Y main`r exposed-,1'y through ,the openings 6, as

indicated inV Figure 1. The outer disks'l: are provided with numerals l5 on their outer surfaces, these numerals being adapti# ed to be exposed through the openings 6. fr'

I The plates 1 are bowed outwardly, as at 16,

and have ,some resiliency,y Because the platesly vare bowed as at 16, the vplatescdo not dragon the numerals 12 and 15 and ob! n y literate them.: By tightening the fadjustfk able pivot member 4, the bowed portions'l.V i

of the"v plates 1 may be compressed upon the outer disks'llL thereby bindingy the rdisks 1li and 11 together,` so that they will` notgturn'` too freely. lFraction disks 17 arek `located between the plates 1v andA areV j ournaled Aon the pivot elements', the spacer 2 .being cut'` away as at 20k in Figure 3 to accommodate,

the fraction disks 17. The fraction disks no` Y numerals and 12 designate a whole num-Y bervisible through the openings, it being possible to rotate the disks 17 so that the numerals 18 thereof, cooperating with the y partition yline 9 will form av fraction, visible Cat through the-openings 7. f

I claim:

1'. `Aidevice of. the class described, comprisinglspaced plates `and means for connecting the plates to form a frame, a pivot member .connecting the plates, the plates` having main openings elongated in the direction .of the length of the frame, 'the main opening of onel plate being located` on .one side of the p-ivotmember, and the-main opening of the `other plate being locatfedo-n the other side of the pivot member, each plate being provided `with an auxiliaryopening disposed between the corresponding l y Ythrough one opening, and the numerals on main opening and the end of the frame, the

auxiliary openings being elongated in the numerals on the outerrsurfaceof the other direction of the width of the frame,I each plate being suppliedon its inner surface I' with a partition line visible through `the auxiliary opening-of the other plate; pairs of disks journaled between the pla-tesa-nd provided with numerals, which arevisible through the auxiliary openings, each numeral on onedisk ofreach pair cooperating with the partit-ionv line to form `the denominator of a fraction, and each numeral on the other Vdisk of each pair cooperating with the partition line to form the `numerator of a fraction of a unit, and an inner disk journaled on the p-ivot member, outer disks Yjournaled on the `pivot member and: located between the` inner disk andthe plates,':the

inner disk being of greater Adiameter than the gouter. disks, thel inner vdisk being pro- V,disk being visible .through one of themain l openings, and the numerals on the other surface of the inner diskand. the numerals on the outer surface .of the other-outerdisk being visible through they other main opening, to denotea number composed of said units. l

.2. A device of the-class described, comprising plates and a spacer therebetween,a

.pivot member' mounted in the-plates, each platehaving-an opening, the rlopenings' being located onopposite sides of the pivot member, yan inner ydisk journaledl on the pivot member, outerfdisks journaled on .the pivot memberand; located between the inner disk and the plates, the inner disk being of greater diameter than the outer disks, the

inner. disk beingprovided on'fits Y.opposite surfaces with numera.ls,.and the: outer surfaces of the outer disks beingprovided with numerals', `the numerals on one surface of the innerrdisk and the numerals yonthe outer surface of one outer xdlsk `being visible the other` surface of Vthe .inner Vdisk andthe outer disk being visible. thro-ugh thel otheropening, the .plates hav-ing outwardly bowed portions which clear the numerals on-v ythe disks, theroutwardly bowed portions of the plates' bearing on. the outer disks attheir peripher1es, 1 the pivot member passing lthroughxthe outwardly bowedfportio-ns of theplates, and beingadjustablezthereby to bind the disks together in adjusted frictional contact.

In testimony that I claim the foregoing as my own, I4 have 'hereto alixed my signature.
